Unclear Wire Payment

Hello. I am trying to figure out the proper procedure to unclear a wire payment so that we can void the original payment.

The background is that our company had made a bank wire payment that eventually was returned to us. We had initially cleared the original manual wire payment out of Cash Management using Manual Clearing - Clear Transactions, thinking that the bankwire was completed (we don't have any feeds coming from the bank to clear/reconcile manual payment).

Would I simply Unclear the original payment and then void the payment? Are there any issues if the original payment was cleared last month and I go to unclear it this month?
